Discovered by Walter Schowalter (Canada, circa 1966).

Unknown, Found Rose.  

USDA zone 2b and warmer.  Very hardy.  

A wild selection I planted this spring is one from my son's garden at Halkirk. Whoever planted it from the wild tried to drape it over an arch trellis instead of planting a root at each base. Even so, I estiimate it was 15 feet tall. The small, cupped, deep rose blossoms are not extremely attractive but it may have potential. - Walter Schowalter 2003
